Maine
- The largest R-hat is NA, indicating chains have not mixed. Running the chains for more iterations may help. See http://mc-stan.org/misc/warnings.html#r-hat
- Bulk Effective Samples Size (ESS) is too low, indicating posterior means and medians may be unreliable. Running the chains for more iterations may help. See http://mc-stan.org/misc/warnings.html#bulk-ess
- Tail Effective Samples Size (ESS) is too low, indicating posterior variances and tail quantiles may be unreliable. Running the chains for more iterations may help. See http://mc-stan.org/misc/warnings.html#tail-ess
